Abstract
The present invention provides a printing plate precursor including a layer which includes particles and is provided at a printing surface side of an aluminum support, in which a modulus of elasticity of the particles is 0.1 GPa or more, and in a case where a Bekk smoothness of an outermost layer surface at the printing surface side is denoted by A second, a specific expression (1) is satisfied; a printing plate precursor laminate; a method for making a printing plate; and a printing method.
Claims15
A method for making a printing plate, comprising:
- providing a printing plate precursor comprising:
- an aluminum support,
- an image recording layer which is provided at a printing surface side of the aluminum support and includes a polymer compound having a particle shape, and
- an optional layer which is provided at the printing surface side,
- wherein the printing plate precursor contains particles in the image recording layer or the optional layer,
- the modulus of elasticity of the particles is 0.7 GPa or more,
- in a case where the Bekk smoothness of an outermost layer surface at the printing surface side is denoted by A second, the following expression (1) is satisfied,
- the polymer compound is thermoplastic polymer particles or a microgel, and
- the thermoplastic polymer particles include styrene and/or acrylonitrile as a constitutional unit:
- A≤1,000 (1);
- image-exposing the printing plate precursor;
- and
- supplying at least one of printing ink or dampening water to remove an unexposed area of the image recording layer on a printing machine and make the printing plate.
